But a source tells ET that despite all the drama, Chmerkovskiy and Lachey will continue to dance together on the hit ABC show.

"The producers wouldn't switch partners because two people aren’t getting along, it’s just par for the course," the source says. "Drama is expected and part of the show. When you train with someone for so many hours so intensely, tensions can run high -- for better or worse. In this case, the intensity led to bickering."

The source also claims Chmerkovskiy is now in "full blown crisis management mode."

"He realizes that he messed up," the source claims. "Vanessa isn’t afraid to stand up to him. She’s a very strong woman."

"He’s on thin ice so you can expect that he’ll be on his best behavior from here one out," the source adds.

However, a second source tells ET that Chmerkovskiy remains in good standing with the show.

"He’s one of the most popular pros on Dancing with the Stars," the source notes. “Maks and Vanessa are continuing to dance together and hopefully they’ll make it all the way to the finals. At the end of the day, Maks is always a professional. This is his job. He just needed personal time away not related to Vanessa.”

A DWTS spokesperson previously told ET, "Maks and Vanessa are returning to rehearsals and will be dancing together on next week's show."
